* Metric Tons: There are 1000 kilograms (kg) in one metric ton (t).

* US Short Tons: There are 907.185 kilograms (kg) in one US short ton (st).

Calculations:

* Metric Tons: 18950 kg / 1000 kg/t = 18.95 metric tons

* US Short Tons: 18950 kg / 907.185 kg/st = 20.91 US short tons

Therefore:

* 18950 kg is equal to 18.95 metric tons

* 18950 kg is equal to 20.91 US short tons
